As shown in fig. 1-3, the utility model provides a height-adjustable seat, including seat body 1 and seat leg 2, seat body 1 is equipped with installation department 111, and seat leg 2 cup joints with installation department 111 mutually, and one of the two that lies in the outside is equipped with the first grafting portion 111a of pass, and one that lies in the inboard is equipped with the second grafting portion 211 of pass or cell type, and the quantity of at least one in first grafting portion 111a, the second grafting portion 211 is a plurality of; the lock further comprises a locking mechanism 3, the locking mechanism 3 comprises a lock cylinder 31, and in a locking state, the lock cylinder 31 can penetrate through the first insertion part 111a and be inserted into the second insertion part 211.

By adopting the structure, when the seat is used, the lock column 31 can be adjusted to be inserted into the first insertion part 111a and/or the second insertion part 211 according to needs, namely, the height of the seat can be adjusted, so that the seat can be used by people with different heights.

For convenience of description, one of the leg 2 and the mounting portion 111 located on the outer side may be referred to as an outer member, and one of the leg 2 and the mounting portion 111 located on the inner side may be referred to as an inner member.

Thus, the above actually includes three schemes: first, the number of the first insertion part 111a is one and the number of the second insertion part 211 is plural, and then the lock cylinder 31 can be actually mounted to the outside member, and then the height of the seat can be adjusted by adjusting the degree of insertion of the inside member and the engagement state of the lock cylinder 31 and the second insertion part 211; secondly, the number of the first inserting-connecting parts 111a is multiple, the number of the second inserting-connecting parts 211 is one, at this time, the installation position of the lock column 31 on the outer member is uncertain, and the aim of adjusting the height of the seat can be achieved by adjusting the lock column 31 to be matched with different first inserting-connecting parts 111 a; third, the number of the first insertion part 111a and the second insertion part 211 is plural.

In comparison, the installation position of the locking mechanism 3 in the above first solution can be basically determined, the locking mechanism 3 does not need to be frequently disassembled and assembled in the height adjustment process, the adjustment process is simpler, the structure is relatively simple, and the embodiment of the present invention is an optimized solution. Of course, the three solutions described above can all achieve the purpose of height adjustment, and in practice, those skilled in the art can select them according to actual needs.

In a specific embodiment, the locking mechanism 3 may further include an elastic member 32, and in the unlocked state, the lock cylinder 31 may be disengaged from the second insertion part 211, and the deformation amount of the elastic member 32 may be increased to gather the elastic force. Thus, when no other external force acts on the lock cylinder 31 and the lock cylinder 31 faces the second mating part 211, the elastic force accumulated by the elastic member 32 is released, so that the lock mechanism 3 can be automatically locked.

In fact, in the locked state, the lock cylinder 31 may also be in a pre-deformed state, that is, the elastic member 32 may also have a certain elastic force in the locked state, which has a positive effect on ensuring the reliability of inserting and locking the lock cylinder 31 in the second inserting portion 211, and can effectively prevent the situation that the seat height is automatically changed due to accidental unlocking.

It should be noted that the elastic member 32 is not necessary, and in the case where the elastic member 32 is not provided, the lock cylinder 31 may be manually inserted and removed to unlock and lock the lock mechanism 3, which also enables the seat height to be adjusted; or, the locking column 31 and the first insertion part 111a may be in threaded connection, and at this time, the locking column 31 and the second insertion part 211 can be separated and inserted only by rotating the locking column 31.

Taking the embodiment with one first insertion part 111a and a plurality of second insertion parts 211 as an example, the locking mechanism 3 may further include a locking piece 33, and the locking piece 33 may be mounted on one of the seat leg 2 and the mounting part 111 on the outer side. In the solution of the figures, the mounting portion 111 may be an outer part, so that the radial dimension of the seat leg 2 may be small, and for this solution the locking piece 33 may be mounted on the outer wall of the mounting portion 111.

When installed, one end of the elastic member 32 may abut against the locking piece 33, and the other end may abut against the lock cylinder 31, so as to provide an elastic supporting force to the lock cylinder 31.

Specifically, referring to fig. 4 and 5, the locking block 33 may be provided with a through hole (not labeled), a limiting member protruding inward along the radial direction may be formed on an inner wall of the through hole, and the locking column 31 may be slidably inserted into the through hole; the elastic member 32 may be a spring, the spring may be sleeved on the lock cylinder 31, and one end of the spring may abut against the limiting member, and the other end of the spring may abut against the lock cylinder 31. At this time, the lock cylinder 31 is also equivalent to a spring cylinder, and can guide the expansion of the spring to avoid the spring from shifting and misplacing in the radial direction in the expansion process.

In operation, the spring may provide a tensile force, and may also provide a compressive force, depending on the location where the spring is installed. For example, referring to the drawings, the limiting member may be disposed at an end of the lock block 33 relatively far from the corresponding leg 21, the left end of the spring may abut against the limiting member, and the right end of the spring may abut against the lock cylinder 31, under such a condition, the spring provides a compressive force, and when the lock cylinder 31 is disengaged from the second inserting portion 211 from right to left, the compression amount of the spring may increase; alternatively, the limiting member may be disposed at an end of the lock block 33 relatively close to the corresponding leg 21, and at this time, the right end of the spring may be connected to the limiting member, and the left end may be connected to the lock cylinder 31, under such a condition, the spring provides a tensile force, and when the lock cylinder 31 is separated from the second inserting portion 211 from right to left, the tensile amount of the spring may be increased.

Besides the spring, the elastic element 32 may also be an elastic element in other forms, such as an elastic block, an elastic ball, a tensile cord, or the like.

In addition, the above-mentioned limiting member only provides one limiting point for the elastic member 32, and the lock cylinder 31 may also provide another limiting point, and specifically, the lock cylinder 31 may be provided with a stepped structure including a large diameter section and a small diameter section, in which case, a step surface between the large diameter section and the small diameter section may serve as another limiting point for the elastic member 32.

Further, the locking mechanism 3 may further include a lock cap 34, the lock cap 34 may be connected to the lock cylinder 31, and when the height of the seat is adjusted, the lock cylinder 31 may be manipulated through the lock cap 34, so as to improve convenience of manipulation. Moreover, the lock cap 34 can also be used as a limiting component of the lock cylinder 31, and can prevent the lock cylinder 31 from being separated from the lock block 33 under the action of the elastic element 32.

How the lock cap 34 is manipulated relates to the connection structure of the lock cap 34 and the lock piece 33, and the connection structure of the lock cylinder 31 and the first insertion-type part 111 a. Taking the no connection relationship between the lock cylinder 31 and the first insertion part 111a as an example: when the lock cap 34 is not connected with the lock block 33, the lock cap 34 can be directly inserted and pulled along the axial direction of the lock column 31; or, when the locking cap 34 is in circumferential clamping fit with the locking block 33, during unlocking, the locking cap 34 can be pulled out partially to release the clamping between the locking cap 34 and the locking block 33, and then the locking cap 34 is rotated in the circumferential direction, so that the locking cap 34 and the locking block 33 can be abutted in the axial direction, and the unlocking state can be maintained, so that the height of the seat can be conveniently adjusted; or, a rotary guiding structure may be provided between the lock cap 34 and the lock block 33, and the lock cap 34 may naturally drive the lock cylinder 31 to separate from the second inserting portion 211 under the action of the rotary guiding structure during the rotation of the lock cap 34; still alternatively, the locking cap 34 and the locking piece 33 may be in threaded engagement, and the unlocking and locking of the lock cylinder 31 may be dependent on the threaded rotation of the nut 34.
